Question

. If f (x) =x square -5 x +7 evaluate,f(2)-f(-1)+f(1/3)​

Answer 1

Answer:

175/4

Step-by-step explanation:

given, f(x) = x^2-5x+7

put x=2 => f(2) = 2^2-5(2)+7= 1

put x=-1 => f(-1)=(-1)^2-5(-1)+7=13

put x=1/3 => f(1/3)= (1/3)^2-5(1/3)+7=49/9

therefore, f(2) - f(-1)+f(1/3)= 1+13+49/9=175/9
